Bill drove 715 miles in 11 hours.
at the same rate, how long would it take him to drive 455 miles?

It would take 7 hours.

Step-by-step explanation:

715/11 = 65

65 miles per hour

455/65 = 7

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.
